What is VPN : Do you really need one in 2023?

Have you observed that When you search for something on the internet, the very next moment you will find ads regarding your search everywhere (apps, e-commerce applications, etc)? Do you still think that your data is private? No right, what do you need to do to stay private? From today, you can stay private anywhere (I can assure you that).

What is VPN

Have you heard the term VPN anywhere before? I don’t know what you think about VPN right now, but you need to change your mindset. Everyone is 👁️‍🗨️watching you online, I know how you feel about it. Don’t worry everything is going to be 😊changed today.

I hope you will know everything after reading this article completely.

Short in time? Here is a quick guide for you:

VPN abbreviated Virtual Private Network, is a software tool that keeps your identity hidden online. It boosts your privacy & security by concealing your IP (assign new IP). All your internet traffic will be routed through a secure encrypted tunnel (unbreakable & your data is unintelligible), and there will be 🚫no Man in the Middle(ISP, Government, 3rd party persons) tracking your online activities.

What is VPN?

VPN is a short form of Virtual Private Network (Nothing hard to understand). This is a software tool that can effectively increase your online privacy. When you are using the 🌐internet instead of routing your traffic from your ISP, they will create a secure encrypted tunnel between the two ends (your device & internet).

While your device will get assigned a new IP (making it impossible for others to trace your hideout). Once the data is out of the tunnel it is handled by the VPN server located in different places all over the world. Then it will be redirected to the destination. So, when you 🔌connect to a VPN server there will be a few things that happen in sequence.

  • Your device will have a new IP Address (Every time you connect)
  • All your data will be encrypted and traveled through a secure tunnel
  • VPN server will handle your request with its DNS

Did you know that 533 million users’ Facebook data has been leaked as per Business insider News?

How does a VPN work?

It’s that simple like turning your 💡 light on when it comes to connecting to a VPN. But, it’s better to know how they work to have a clear picture of their role in your privacy. All you will do is hit the “Quick Connect” button on your VPN home screen. Rest everything will happen in the background.

  • First, it will create a secure encryption tunnel to route your internet traffic coming from ISP (Don’t worry they can’t look into data as it is encrypted).
  • Once the required data reaches the VPN server, it will get decrypted. Then it will hit the internet and bounce back with a reply (the one you require from the internet).
  • The VPN server will encrypt the data again and send it to your device (where the data will be decrypted). So, you can understand the request.

You won’t find any difference in accessing the internet or any additional settings needed to browse. You will get an additional layer of protection to prevent snoopers, government, and third-party members from stealing your information through your original IP.

So, here is the scenario that happened with two friends in a coffee 🏬shop. Both of them are connected to the free Wi-Fi available in the shop (One is using a VPN). They start downloading torrents, browsing sites, opening important files, etc. The very next day, the person’s (who not using a VPN) phone got hacked and everything got leaked digital credit cards, PINs, passwords, etc saved on his phone.

But 🤔how? Why the other guy is safe? Because he used a VPN which keeps his IP safe, while the hacker attacked the server IP. There’s nothing he can get from the server (as it doesn’t store anything).

Well, a VPN has several benefits. Also, there are several types of VPNs in the market, 😵confused? I am here for a cause…

It’s found in Dzone reports that different countries’ ISP is selling their user data for profits.

Types of VPN

Generally, VPNs are classified into several categories based on the purpose they are being used for. But the core functionality remains the same…

  • Site-to-Site VPN
  • Remote Access VPN

Site-to-Site VPN

Site-to-Site VPN also known as Router-to-Router VPN is largely used in companies or organizations with branches located in different places (they use this type of VPN to connect to different office locations).

This type of VPN can be broken down into two types again.

  • Intranet VPN: When different branches of a single parent company want to connect using a VPN, then it will be intranet VPN (Site to Site).
  • Extranet VPN: When different companies connect, then it will be an extranet-based VPN.

Either way, it will create an imaginary bridge between networks connecting several offices and connecting them through the internet.

📝Note: In site-to-site, one router reacts as a VPN client and the other as the VPN server (authentication will be done between the two)

Remote Access VPN

Remote Access VPN will create a private network, so you can access all its resources remotely, While the connection between the users and the internet remains secure & private. These types of VPNs are preferred for home & personal use, even for business use.

When an employee is off on a trip or vacation. He/she can use a VPN to connect to the company’s private network and get the required files on a private network.

Role of VPN in user privacy

VPN technology is very essential for user privacy & security. When you connect to a VPN server create an encrypted tunnel and route the internet traffic with your newly assigned IP. All of your online activities will be hidden from anyone preventing Man in the Middle attacks.

This is very true when it comes to connecting to public Wi-Fi, hotspot, etc. So with a VPN connection even when you are on a public or private network, you will be secure all the time. As your IP is hidden, it acts like a proxy server (intermediate between you and the Internet). No malicious website or hacker can get your real location.

VPN protocols

During creating a secure encryption tunnel, there are some sets of protocols (rules) that can be tweaked for better security & speed. While some protocols are good at security & some are good at speed, the most common VPN protocols are:


What is VPN : Do you really need one in 2023?

The name suggests itself that this protocol is open-source & widely used. OpenVPN is the best choice for most device platforms like Windows, Android, Linux, Routers, etc. This protocol can be used to create point-to-point or site-to-site connections and build based on SSL & TLS protocol. But the only downside of this protocol is that it won’t work for macOS and iOS. So you have to choose between other protocols available on the VPN provider.


What is VPN : Do you really need one in 2023?

WireGuard is a relatively new protocol to the VPN industry, but the most preferred one (huge popularity). As this protocol runs on the Linux kernel, it supports all platforms and is better than OpenVPN. But this protocol is still in the development stage (beta), yet better than OpenVPN. If your VPN provider has WireGuard, choose this protocol for balanced performance.


What is VPN : Do you really need one in 2023?

The name is coined as IKEv2/IPSec as this protocol is based on IPSec, so this protocol can quickly switch between any two networks. This can be the ideal choice for mobiles (frequent switches between mobile networks & Wi-Fi). There are some sources on the internet claiming that IKEv2 is faster than OpenVPN, but in reality, OpenVPN is much better & faster.


What is VPN : Do you really need one in 2023?

This protocol uses L2TP (Layer 2 Tunneling Protocol )for establishing a secure tunnel connection and IPSec to encrypt the data. There will be two L2TP endpoints creating a tunnel and IPSec for encrypting the data. I recommend using this protocol if OpenVPN is not available for your device.


What is VPN : Do you really need one in 2023?

Point-to-Point Tunneling Protocol is another widely used VPN protocol, though there are some leaks found in this protocol. It’s advisable to use this one when you want speed over safety (when you want to stream with high speed).


What is VPN : Do you really need one in 2023?

This protocol is developed by Microsoft so it works only on Windows. So, there is not much popularity in this protocol but still available on some VPN providers.

Double VPN

What is VPN : Do you really need one in 2023?

Have you heard the term double VPN? What is this? Some VPN providers like NordVPN have this feature, Double VPN is nothing but using two VPN servers instead of one (shown in the picture). Sometimes this is referred to as a multi-hop feature, despite only a few VPN service providers offering this feature there is huge 🔥popularity for this one.

The reason behind not providing this feature is slower internet speed (200% ⤴️high security). When your traffic is routed through two servers (located far distance apart) slow speed is inevitable (double encryption). But this is a powerful option for certain people (Anonymous🐱‍💻). If you are dealing with very sensitive data (additional security is always a good choice).

Double VPN is a bonus feature (not a mandatory one). Well, there are some downsides & upsides to this feature. Let’s begin with the upsides

  • Double Encryption: You have witnessed that the traffic will be encrypted twice (virtually unbreakable).
  • Extra IP: When you connect to the second server which hides the IP of the first server hiding your original IP again.
  • Protocol Cocktail: If you use some protocol for the first connection and still have choices to choose another protocol available from the service provider (protocol mix).

Con’s of double VPN

Never use this feature by default. That’s why many providers will don’t provide this feature. If you want to torrent safely or stream something private🔒, it’s fine to use this option after knowing the downsides.

  • Slow Speeds: Double VPN’s major drawback is slow speeds (a normal VPN connection slows down your speed). When you add a layer to it, you will lose a lot of your speed potential (nearly up to 50%). Therefore you can’t enjoy 4K movies or download huge files at a faster rate.
  • Can’t use Tor over VPN: When you enable Double VPN, you can’t use Tor over the VPN feature (if available).
  • Power Consumption: Double VPN feature drains your battery faster than the usual VPN connection (plugin devices won’t be considered).
  • Low Server Choice: For the first connection you can select any server, but when it comes to double VPN second server you will be limited to 50+ servers to choose from.

📝Note: Any service that doesn’t have this feature can be also the best VPN.

VPN Chaining

What is VPN : Do you really need one in 2023?

Do you ever doubt in your mind about using more than 2 VPNs at a time? It’s VPN chaining that helps in improving online privacy. This depends on how many VPNs you want to use between your system & internet.

It grows like an endless 🔗chain, you can achieve this by connecting to more VPN providers at a time (VPN chaining improves your anonymity). But there are some disadvantages too (maintaining multiple VPN accounts). At any instance, you might forget the password of any of your accounts and try resetting it through forget mail procedure (tedious).

If you want to skip all these hectic procedures, try the best password managers available in 2023.

VPN vs Proxy

Both VPN & Proxy will provide you with a high level of privacy (but the way they do is different).

  • Proxy: A proxy acts as a gateway- best for browsing, and accessing restricted content (Excellent for misleading & misdirections)
  • VPN: A VPN is a software client tool & that establishes a secure tunnel with a VPN server replacing your original IP. This will work for all the applications system-wide.

Privacy & security matter these days, regardless of your personal or professional data. Make sure that you are investing in the right thing. To get the most from your bucks, sign up for the VPN today.

Limitations of VPN

I agree that everything has cons too, it’s the same for a VPN as well. Though it’s primarily for privacy & security, it will not protect you from all cybersecurity attacks. Of course, VPN will provide an additional layer of anonymity to your online activities.

  • It can’t prevent you from the virus injected through clicking Ads or from downloaded files. It’s an antivirus duty to do.
  • Google service will still recognize your accounts even when you are connected to a VPN (changes your IP), it’s the same for services like Facebook as they correlate with your browsing 🍪cookies.
  • When you turn on 📍GPS, your device location can be recognized even when you are connected to a US server.
  • A VPN will slow down your internet speeds (due to encryption and tunneling). But don’t worry those are not noticeable with some best premium VPNs.
  • Some VPNs might not work well in banned countries, you need to make sure that you don’t travel without any backups to such countries (countries like China, Russia, etc).

Though a VPN plays a vital role in your online privacy. Also, you need to ensure some things like cleaning cookies frequently and beware of the limitations of the VPN.

Why not free VPNs?

What is VPN : Do you really need one in 2023?

Of course, there are an ample number of free VPNs available in the market. But free VPNs are less secure, keeping the cost aside they ruin your online experience and make you suffer in the future.

As per the data reports collected from the free VPN users, they are a threat to your privacy. Here’s why…

  • Monitor & Sell logged data: VPNs should be a protective layer and secure your data. But free VPNs rely on users’ data (milking 🐄cows) for revenue. The more they sell, the more they gain while your privacy is at risk⚠️.
  • Leak your IP Address: While premium VPNs create a secure encrypted tunnel, free VPNs have tons of 🕳️holes in them. So, there is DNS or IP leak protection while all other hackers prey on your activities.
  • Not Safe: Free VPN solution is always risky (dangerous to your privacy & security), and many 🐠fishy services are meant to serve your personal information to others.
  • Aggressive Ads: There are ways to aggressive ads displayed on the free VPNs, they can’t even block the website ads. There is no other option except to rely on the best ad blockers in the market.
  • Malware Exposure: Some users witnessed that free VPN brought malware to their devices (high risk of a data breach). While they won’t take any responsibility, neither for any issues using the application.


If you are new to VPNs and just getting started with them, check out the best VPNs. It’s always recommended to use a VPN all the time when you are on the internet. It might be anything you want, whether you want to unblock any geo-blocked website or streaming services.
